The oil and gas sector is rapidly changing due to variations in commodity prices, technology innovations, and emerging regulatory programs. The Intermountain Region is especially impacted by exploration
and production emissions from the oil and gas industry, and the West more broadly by emissions from the transport and use of those fuels. NAAQS exceedances during winter in production regions of Utah and
Wyoming have demonstrated localized effects, while the contributions from exploration and production in the wider region on summer ozone is still being assessed. In addition, this sector must be considered
for Regional Haze planning. Studies point to improvements in the emissions inventory as being one of the most needed products to improve performance of the air quality models and will be a key focus of this
work group.

Responsibilities and Deliverables:

The Oil and Gas Work Group is:

Responsible for addressing the data and analysis elements, topics, and issues under the Oil and Gas section of the WRAP Workplan (Section I.D.1)

Responsible for providing oversight and coordinating efforts with projects and activities across the WRAP and with other groups related to Oil and Gas

The Oil and Gas Work Group will:

Prepare a detailed Workplan for the TSC as inputs to update the WRAP annual Workplan for achieving these Oil and Gas analysis and planning elements. These will include:

Schedule for work product completion

Budget estimates of outside funding support needed

Timing of progress reports

Milestones to support timely and necessary Oil and Gas analysis activities

Final Report (March 5, 2020) and
Inventory Spreadsheet (final version of March 5, 2020) for the “Continuation of Historical Trends” projection inventory. These data will be used in modeling and control analyses for Regional Haze planning.

State of Colorado projections methodology (PDF) (January 2, 2020, data are included in the Final Report and Inventory Spreadsheet above).

State of New Mexico updated projections data from early Feb. 2020 are included in the Final Report and Inventory Spreadsheet above.

The Revised Final Report and
Inventory Spreadsheet were completed in mid-Sept. and posted on Sept. 23, 2019.
These files completely replace the previously posted July 2019 report and spreadsheet, while the gas profile information posted in July
is unchanged. The July report and spreadsheet files have been removed to avoid confusion. The Revised Final Report includes updates from the July postings to include the:
1) Colorado O&G emissions based on new inventories provided by Colorado Department of Public Health and Environment and Southern Ute Indian Tribe and
2) Williston Basin casinghead gas emission inventory to correct emissions that were biased low based on EPA O&G Tool inputs.

National Oil & Gas Emissions Committee’s Information Repository, hosted by the Intermountain West Data Warehouse – Western Air Quality Study (IWDW-WAQS), stores and allows access to information of
interest to state air agencies, EPA, and others about Oil and Gas activity and emissions data, and supporting information across the U.S.
